Hi. First I'd like to thank U all for the very helpful project - I now have a fully functional MacbookPro :-)
I have read many reports about problems with the internal microphone but now I've found a way to make it work: I use vanilla 2.6.18 with the 2.6.18 mactel patches on a MacbookPro I found that 3 settings affect the microphone and need to be whacked (especially after resume - it seems that the resume code doesn't properly reset them; they are maybe not initialized either). If I run amixer sset 'Input Source' 'Line' amixer sset 'Input Source' 'Mic' amixer sset Capture '100%' toggle amixer sset Capture '100%' toggle amixer sset Mux 0 amixer sset Mux '100%' then I have a working microphone (until the next resume). (note that in order to make suspend/resume work I needed some additional [not sound related] patches - I'll post them some time soon...)
